Concord, CA Short-Term Rentals: Occupancy Limits (2026)

Concord does not publish a stand-alone STR occupancy formula separate from its general residential occupancy and nuisance standards, but typical enforcement follows the California Building Code minimum room sizes and HUD's long-standing 2+1 guideline (two occupants per bedroom plus one additional person per unit, often expressed as 2 per bedroom plus 2) to assess overcrowding. Operators commonly list an occupancy cap on their platform equal to two adults per legal bedroom plus a small allowance for small children or infants. A legal bedroom under the California Building and Residential Codes must have a minimum floor area (typically 70 sq ft, with at least 50 sq ft for each additional occupant beyond one), a ceiling height of at least 7 feet, a window with emergency egress, heating, and a closet is customary but not strictly required. Rooms without egress windows (converted garages, basements, attics) are not legal sleeping rooms and cannot be counted. Concord's noise ordinance and public nuisance provisions apply regardless of occupancy count - even a compliant guest number can trigger violations if noise exceeds residential limits (typically quiet hours 10 PM to 7 AM) or parking spills into neighbor access. Parties, weddings, and events at STRs are a frequent nuisance trigger; operators should prohibit events in house rules and include platform-enforceable language. Repeated nuisance calls can lead to revocation of the TOT registration certificate under the city's administrative enforcement process.
